Description

Lane Forming Method {A FORMING METHOD OF THE ROAD LANE}

The present invention relates to a lane forming method, and more particularly, to a lane forming method that can be economically easy to construct and maintain, improve durability and stain resistance, and can continuously maintain visibility at rain and night. It is about.

The road has a center lane and a driving lane to help the driver. Lanes should have good durability, stain resistance, adhesion, discoloration resistance, and visibility, and the importance of night visibility is increasing more recently for the increasing trend of drivers after sunset and accident prevention, but the effect is temporary.

In general, the paint used in the lane includes an acrylate-based resin, a curing agent and a pigment, and in some cases, various additives are used to improve durability, stain resistance, adhesion, discoloration resistance, or visibility. Recently, in Korea Patent No. 10-933923, glass beads and cores were made of spherical ceramics, and a special optical reflector on the surface of which was coated with ceramic glass beads was applied. Or more research on the adhesion of the optical reflector with the paint is required.

The present invention has been made to solve the problems of the prior art as described above, economical construction and maintenance as well as providing a lane forming method that can improve durability, pollution resistance, and in particular, night visibility is improved. It aims to do it.

In order to solve the above problems,

The present invention mixes 100 parts by weight of acrylic paint, 70-100 parts by weight of a pigment and a silanol of a ceramic powder and 1-50 parts by weight of a composite resin in which the hydroxyl group of the resin is multi-linked by dehydration condensation or hydrogen bonding. After applying the lane material obtained by stirring, the glass bead is sprayed before the lane material is completely cured, and the lane material is cured by surrounding the glass bead projection, and the lane material is cured into a crater shape around the glass bead. It provides a lane forming method.

The lane forming method according to the present invention does not require a primer process, and is economically easy to construct and maintain, and also easy to implement colors when reflecting at night due to glass beads, and adhesion to asphalt and concrete surfaces, durability, and resistance to It is possible to improve the contamination, and in particular to improve night visibility. Particularly, in the case of a concrete road, the color visibility of the lane was low at night, but the lane forming method of the present invention can significantly increase the night lane color visibility even in the concrete road.

Hereinafter, the present invention will be described in more detail.

In the lane forming method of the present invention, 100 parts by weight of an acrylic paint, 70-100 parts by weight of a pigment and a silanol of a ceramic powder and a hydroxyl group of a resin are multi-linked by a dehydration condensation or hydrogen bond. After applying the lane material obtained by mixing and stirring the weight part, glass beads are sprayed before the lane material is completely cured so that the projections are formed while the lane material surrounds the glass beads.

In the lane forming method of the present invention, the lane includes all lanes formed on an asphalt road or a concrete road, and more particularly, in a lane formed on a concrete road.

The lane material used in the lane forming method of the present invention is 100 parts by weight of acrylic paint, 50-100 parts by weight of pigment and 1-50 parts by weight of a composite resin in which the silanol of the ceramic powder and the hydroxy group of the resin are multi-linked by dehydration condensation or hydrogen bonding. Obtained by mixing and stirring.

The acrylic paints and pigments may be conventionally known acrylic paints and pigments that are acrylic paints and pigments that can be used as a lane material.

The composite resin is a resin in which the silanol group of the ceramic powder and the hydroxy group of the resin are multi-linked by dehydration or hydrogen bonding, and the ceramic powder preferably has a particle size of 1 nm-500 um. The smaller the particle size, the more the specific surface area increases, which is advantageous to reduce the surface tension of the resin.However, when the particle size exceeds 500 um, agglomeration occurs between particles when the ceramic powder and the resin are mixed. Can be blocked. More preferably, the particle diameter of 100 nm to 100 um is good for ease of operation and physical properties of the lane surface. The ceramic powder can reduce the fluidity of the resin resulting from the increase in oil absorption due to the increase in the specific surface area of the talc powder, calcium carbonate, and the like used in the conventional paint.

The resin may be, for example, a room temperature curable organic liquid resin such as epoxy, acrylic, urethane, polyester, or polyvinyl chloride, and is preferably acrylic or epoxy resin.

In the present invention, the ceramic powder is preferably contained in 10 to 400 parts by weight based on 100 parts by weight of the resin solid content, when the content is less than 10 parts by weight, the viscosity of the lane material is lowered and shrinkage expansion after curing This may increase, if the content exceeds 400 parts by weight, the viscosity may increase too much, the resin content may be lowered, and the strength of the lane surface may be lowered. There is concern. More preferably, the content of the ceramic powder is included in 20 parts by weight to 150 parts by weight of the resin, and in this case, both workability and physical properties of the lane surface may be satisfied, and in particular, the glass beads may be more prevented from falling off. have.

Preferably, the composite resin preferably has electrical conductivity, and the composite resin preferably has an electrical resistance before curing of 10-10 ¹⁰ ohms (Ω). In this case, the adhesion to the road, the adhesion to the glass beads, and the stain resistance can be satisfied at the same time.

In the lane forming method of the present invention, when the lane material is applied to a road surface (specifically, a concrete road surface), the composite material may be directly applied to the road without coating of a primer, and the coating thickness may be arbitrarily adjusted when the lane material is applied to the road. It is preferable to apply in a thickness of preferably 0.01 to 30 mm. As a coating method, a well-known coating method may be used, and, as an example, spray coating may be used.

In the lane forming method of the present invention, the glass beads are sprayed onto the surface of the coated lane material prior to the complete curing of the lane material so that the projections are formed while the lane material surrounds the glass beads.

As the glass beads used in the present invention, glass beads of spherical shape, elliptical shape, or equivalent shape may be used. Preferably, the glass beads have a particle size of 0.01 um to 3 mm, more preferably 0.3. It is preferable that it is to 1.5 mm. They may also exhibit various shapes and properties by the combination of beads having a small particle size of several μm and a large particle size of several mm. When using glass beads having a particle size within the above range it can satisfy the adhesion, durability, stain resistance and visibility at the same time. It is also possible to use color beads that have a color that matches the lane color, if necessary.

In addition, the glass beads are preferably sprayed such that 40 to 90% by volume of the glass beads and 10 to 60% by volume of the glass beads are applied to the coating layer of the lane material. This can be achieved by adjusting the tension of the lane material. More preferably, the glass beads exposed to the outside are 20 to 40% by volume. In this case, it is possible to satisfy the effect of improving the adhesion and visibility of the lane material and glass beads, in particular, night visibility, and also to improve the durability and contamination resistance of the lane surface.

Such glass beads are preferably used in an amount of 0.1 to 50 parts by weight, more preferably 1 to 30 parts by weight, even more preferably 5 to 20 parts by weight, based on 100 parts by weight of the lane material. If the glass bead content is too small, the effect of improving visibility and fouling resistance is insignificant, and in the case of using the glass bead too much, there is a problem that glass beads may be dropped after the lane material is cured.

As described above, the glass beads sprayed on the upper surface of the lane material coating surface before curing of the lane material are fixed by the lane material 2 applied to the road 1 as shown in FIG. 4 and protrude from the upper part of the lane material 2. The formed glass bead projections 3 are formed.

The lane formed according to the lane method of the present invention has excellent adhesion to the road, adhesion to the glass beads, durability, stain resistance, visibility is improved, and may have improved night visibility in particular.
